The piece was the Daily News' cover story, and when readers opened to the column, they found a large photo of Biles, mid-leap, smack in the center of the copy. A caption reads: 'Gabby Douglas: Olympic gold medalist, need we say more?'

"It makes you want to bash your head against a wall," Polaneczky told NBC10. "I'm mortified."

A photo of Biles also appeared in the online story Wednesday morning. It was quickly changed when the mistake was noticed, Polaneczky said.

The Philadelphia Daily News, like other newspapers across the country, has been saddled with declining circulation and ad revenue. There have been several rounds of layoffs amid a series of ownership changes. The paper's newsroom staff recently underwent a merger with those at the Philadelphia Inquirer and Philly.com.
